Subject [jira] Created: (CLK-736) function getPageClassList has incorrect return type
Date Mon, 06 Dec 2010 09:30:14 GMT
function getPageClassList has incorrect return type

                 Key: CLK-736
             Project: Click
          Issue Type: Bug
          Components: core
            Reporter: Leszek Piotrowicz
            Priority: Minor

function getPageClassList from class ConfigService
has an incorrect signature

public List<? extends Page> getPageClassList();

while it should be

public List<Class<? extends Page>> getPageClassList();

This function when used causes sometimes ClassCastException. However this is not repeatable.
I assume that javac compiler generates code which try to cast to incorrect generic type.
Loop construction like
for(Class<? extends Page> clazz : configService.getPageClassList()) {...} is rejected
by java compiler

Please correct the signature in ConfigService and its implementation in XmlConfigService
